7. Let duration be equal to action object's duration property if it is not undefined, or tick duration otherwise.

8. If duration is greater than 0 and inside any implementation-defined bounds, asynchronously wait for an implementation defined amount of time to pass.
   This wait allows the implementation to model the overall pointer move as a series of small movements occurring at an implementation defined rate (e.g. one movement per vsync).

(A lengthy specfication of splitting the pointer move event over multiple smaller steps).

Currently we do a single atomic movement from the start to the end.
